Wheat cultivar ofree for improvement of gluten intolerance and wheat-dependent exercise-induced anaphylaxis
The present invention relates to Ofree, a novel wheat cultivar produced by crossing Keumkang wheat and Olgeuru wheat, in which low-molecular-weight glutenin subunit (LMW-GS) alleles located at the Glu-B3 loci (major cause of gluten intolerance) and ω-5 gliadin genes (major cause of wheat-dependent exercise-induced anaphylaxis (WDEIA)) have been deleted; a method of developing a new wheat cultivar using Ofree; wheat flour produced from Ofree; a method of producing a processed food using the wheat flour; and a processed food produced by the aforementioned production method. It is expected that Ofree provided in the present invention can be widely used for the production of processed foods capable of preventing the onset of celiac disease caused by gluten intolerance and the onset of WDEIA.
1. A new wheat cultivar in which low-molecular-weight glutenin subunit (LMW-GS) alleles located at Glu-B3 loci have been deleted, the new wheat cultivar is deposited with a deposition number KACC88001BP.
2. A method of developing an improved wheat cultivar, the method including using the new wheat cultivar according to claim 1 as a father plant or a mother plant for crossing with another wheat cultivar.
3. The method of claim 2 , wherein the other wheat cultivar is Jokyung wheat, Jopoom wheat, Baekjoong wheat, or Goso wheat.
4. Wheat flour obtained by milling the new wheat cultivar according to claim 1 .
5. A food composition including the wheat flour according to claim 4 .
6. The food composition according to claim 5 , wherein the food composition is noodles, cookies, or bread.
7. A method of producing a processed food, the method including:
(a) obtaining wheat flour by milling the new wheat cultivar according to claim 1 ;
(b) preparing a dough containing the wheat flour; and
(c) processing the dough.
8. The method according to claim 7 , further comprising:
mixing the wheat flour obtained from (a) with wheat flour obtained from another wheat cultivar to form mixed flour.
9. The method according to claim 8 , wherein the wheat flour obtained from (a) is included in the mixed flour in an amount of 50 to 99% v/v.
10. The method according to claim 8 , wherein the another wheat cultivar is selected from the group consisting of Keumkang wheat, Olgeuru wheat, Jokyung wheat, Jopoom wheat, Baekjoong wheat, Goso wheat, and combinations thereof.
